BioAssay: AID 146280

Evaluation as substrate of Neuronal nitric oxide synthase by hemoglobin assay using NOHA as control

Because of the double-edged nature of NO, the development of isoform-selective NOS substrates is a highly desirable goal. Given the striking similarity in the heme active sites of the three NOS isoforms, it presents an challenging problem. Several N-aryl-N'-hydroxyguanidines have recently been shown as substrates that are selective for iNOS over nNOS. Here, we report the first success that 3 is a good substrate for nNOS (70% activity of NOHA, K(m) approximately 40 +/- 6 microM) over iNOS. ..more

Title: Isoform-selective substrates of nitric oxide synthase.

Abstract: Because of the double-edged nature of NO, the development of isoform-selective NOS substrates is a highly desirable goal. Given the striking similarity in the heme active sites of the three NOS isoforms, it presents an challenging problem. Several N-aryl-N'-hydroxyguanidines have recently been shown as substrates that are selective for iNOS over nNOS. Here, we report the first success that 3 is a good substrate for nNOS (70% activity of NOHA, K(m) approximately 40 +/- 6 microM) over iNOS.
